Evaluation of electromyographic monitoring during insertion of thoracic pedicle screws.
We prospectively studied the use of intercostal EMG monitoring as an indicator of the accuracy of the placement of pedicle screws in the thoracic spine. We investigated 95 thoracic pedicles in 17 patients. Before insertion of the screw, the surgeon recorded his assessment of the integrity of the pedicle track. We then stimulated the track using a K-wire pedicle probe connected to a constant cur...
متن کاملNeurophysiological assessment of thoracic and cervical pedicle screw integrity.
Transpedicular instrumentation of the thoracic and cervical spine is technically more difficult than at lumbar levels because of narrower pedicles and less sensitive intraoperative fluoroscopic assessment. Furthermore, the potential implications of a misplaced screw are greater because of the close proximity of the spinal cord and vertebral artery. Real-time confirmation of correct pedicle scre...
متن کاملAccuracy of Intraoperative Computed Tomography–Based Navigation for Placement of Percutaneous Pedicle Screws
MISS techniques have gained recent popularity. The proposed benefits of these techniques include reduced tissue trauma, reduced blood loss, less perioperative pain, and a quicker recovery and return to normal activities. The purpose of this study was to evaluate the accuracy of intraoperative computed tomography (CT)-based navigation for placement of percutaneous pedicle screws in a cadaveric m...
متن کاملPercutaneous lumbar and thoracic pedicle screws: a trauma experience.
DESIGN Retrospective case study. OBJECTIVE Percutaneous pedicle screw (PPS) techniques do not allow direct visualization and may lead to erroneous screw placement. A technique utilizing only fluoroscopy is described. Verification of its accuracy and morphometric validation are presented. BACKGROUND Minimally invasive spine surgical techniques, particularly PPS placement, have been growing i...
متن کاملCortical bone trajectory screws placement via pedicle or pedicle rib unit in the pediatric thoracic spine (T9-T12)
Thoracic cortical bone trajectory (CBT) screw fixation can maximize the thread contact with cortical bone, and it is 53.8% higher than that of the traditional pedicle screws. Moreover, it can also enable less tissue dissection and retraction for reduced muscle disruption.Eighty pediatric patients are divided into 4 age groups and their thoracic vertebrae are analyzed on computed tomography (CT)...
